Abstract (en)

A cordless telephone system includes a single base unit (120) and at least two remote handunits (100,150). The base unit (120) employs two transmitter channels (292,288,284,280,275,294,290,286,282,275) coupled together through a low impedance and coupled to a single antenna (122), and the transmitter channels include voltage controlled crystal oscillators (VCXOs) (284,286) and frequency tripler circuitry (288,290), rather than PLLs in order to keep intermodulation distortion at the outputs of the transmitter amplifiers to a minimum. <IMAGE>
